Again, complete BS!
From http://jbig2.com/
The advantage of JBIG2 encoding of your company's documents is that this ITU-approved standard, unlike TIFF G4 and TIFF-based PDF, is font-based and allows for efficient encoding of a fully-searchable text layer.
WHERE IS THE TEXT LAYER! IT'S NOT THERE!!!
Now, knowing that a font based compression did not create a text layer, how did the document end up with multiple letter and box pixel for pixel duplications? Answer - cut and paste!
Spread your stupid lies somewhere else!

The way JBIG2 works is that is searches a document for areas that match known fonts. When it finds a match, is removes it from the image layer, and adds it to a text layer. This has two large advantages, 1) storing text data as an image is VERY inefficient, and 2) you can not search an image data for text, only text layers. So after JBIG2 compression, text in a document will be in the text layer, and can be found by a simple search with ctrl+F.
The idea that compression, especially JBIG2 compression created anomalies in the document is ludicrous. The idea that JBIG2 was used was first brought forward to explain the letters that are pixel for pixel copies throughout the document. But that was quickly shot down when it was pointed out that the letters where still in image layers, and not in a text layer, therefore a substitution type algorithm was not used.
